Application filed June 18, 1886.

T 6M whom it may concern:

Be it known that I, CHARLES A. IIUssEY, of NGWYOlk, in the county and State of New York, have invented a certain. new and useful Improvcimait in Electric 'lime-lndicating Systems, of which the l'ollowingis aspecification.

I will describe an electric time-indicating system embodying my improvement, and then point out the various novel features in claims.

The accompanying drawing is a diagram illustrating my improvement.

All the parts which are located in the office where the system is controlled are surrounded by a line,ad ja(-ent to which I have marked the word ()tllce.

A designates the sweep second arbor in'a primary mechanical clock or regulator. This clock or regulator may be of any suitable kind and operated by a weight or spring. The shaft A, it must be understood makes one complete rotation during each minute. On the shalt A is afiixed a wheel, A, having a notch, a, in its periphery. Adjacent to the wheel A a wheel, A, is arranged in the primary clock or regulator. As shown, the wheel A is journaled loosely in a swinging arm, A which is pivotally connected to a rod, A, located in the primary clock or regulator. The wheel A? rests upon the periphery of the wheel A. Whenever the notch a in the pcriphery of the wheel A comes opposite the wheel A'", the latter drops into it. The arm A of course descends with the wheel A when the latter drops into the notch.

A" designates a rod in the primary clock or regulator, which has at the lower end an offset or shoulder, a, extending under theswinging arm A. As shown, the arm A has aprojection, a opposite the offset or shoulder a of the rod A \Vhen the swinging arm A descends on the dropping of the wheel A into the notch a of the wheel A, the projection (6 makes contact with the offset or shoulder a of the swinging arm A. The rods A A and the swinging arm A are to he made of metal. The other parts which I have mentioned may or maynot be of metal. The rods A A are to be insulated from each other. This may be done by supporting them in a frame of insulating material, A, or by interposing pieces of insulating material between them and the frameif the'latter is not made of insulating Sa'l'itti No. 205,564. (X0 model.)

material. The red A has connected to it a wire, A, which extends to one pole of an electric battery, A From the other pole of the battery A a wire, A, extends. A wire, A extends from the rod A. \Vhenevcr the swinging arm A descends in. the manner which I have explained, and its projection makes contact with offset or shoulder a of the rod A", the wires A and A are in electrical communication; This electrical eomnninication will be only momentary, owing to the fact that the notch a of the wheel A is of very slightextent. The notch is preferably so shortin the direction of the periphery of the wheel A that the contact ot'theprojection a of the swinging arm A with the offsetor shoulder a of the red A will exist only for two seconds during each rotation of the sweep second-shalt A. The wire A is connected to a binding-post, A,with which one end of the wire of an electromagnet, A, is connected. The wire A is connected to a binding-post, r with which the other end of the wire of the electroanagnet A is connected.

It will be understood, in view of the foregoing explanation, that whenever the swingingarm A is allowed to drop so that its projection a? will make contact with the offset or shoulder a of the red A, the electromagnet A will be momentarily energized from the battery A The electroanagnet A has combined with it a swinging armature, A. A spring, a, tends to pull the armature away from the electromagnet. The armature is attracted toward the poles of the electroanagnet whenever the latter is energized. The armature A vibrates between two metal contactpieces, a" a, shown as consisting of screws in order to be adjustable. Normally the armature will be held against the contact-piece a by the spring a. XVhen the electro-magnet is energized, the

armature will be vibrated over against the contact-piece a momentarily.

B designates an electro-magnct having combined with it an armature, B impelled in one direction by a spring, (Z, and moved in the other direction by the attractive force of the electromagnet B. The armature B" vibrates between two metal contactpieces, (shown as consisting of adjustable screws) b Z1 Non mally the armature B is held against the contact-piece b. .Vhen attracted by the electro magnet B, it is swung against the contactpiece If".

D designates a main battery for sending currents of electricity over line-wires G C 0 The line-wires O G extend from the armatures A B of the electro-magnets A- B. The line-wire 0 extends from one pole of the bat tery D. A wire, D, extends from one pole of the battery D to a binding-post, d, and the latter is connected by a wire, D", with the contact-piece If. A wire, D, extends from the binding-post d to a bindiiigpost, (Z which is connected by a wire, D, to the contact-piece a It will be seen that as the armatures A B are normally separated from the contactpieces a b no current passes from the battery D ordinarily. WVhenever the electro-magnet A is energized, so that it shifts its armature A against the contact-piece a, an electric circuit will be completed from the battery D in one direction along the wire D to the wire D thence along the wire D to the armature A,

and thence along the line-wire C, and in the other direction along the line-wire 0 If the electro-magnet B is energized, its armature B will be shifted over to the contact-piece b whereupon. an electric circuit will be completed from the battery D along the wire D to the wire D along the latter to the armature B, and from said armature to the linewire 0, and in the other direction along the line-wire G".

I will here remark, in order to conduce to a clear understanding of my improvement, that an electric current is caused by energizingthe electro-magnct A to flow over the linewires 0 O to cause the electric or secondary clocks which I employ to record hours and minutes, and that the electric current is caused by energizing the eleetro-magnet B to flow from the battery D over the line-wires C C for the purpose of causing other parts of the electric or secondary clocks to record days, in order that they may serve as calendars.

I will now describe the mechanism whereby the operation of the electromagnet B is controlled. A wire, B, extends from the wire A to a binding-post, which is connected with one end of the wire of the electro-magnet B. The other end of the wire of the electro-magnet B is connected to a binding-post with which a wire, B, is also connected. The wire B* is connected to a rod, B in the primary mechanical clock or regulator. This rod is to be made of metal, and has at the lower end an offset or shoulder, b.

B is a swinging arm,made of metal, having a projection, b opposite the offset or shoulder b", of the rod B The swinging arm B has journals supported by bearings consisting of screwsor pins b fitted in metal rods B B*,arranged in the primary clock or regulator.

The rod B is connected by a wire, B", with A Whenever the swinging arm B'is allowed to descend, so that its projection b will make contact with the ofl'set or shoulder b of the rod B, an electric circuit will be completed from the battery A along the wire A to the wire B thence through the rod B to the swingingarm B, thence over the latter to the rrod B and thence along the wire B to one end of the wire of the electro-magnet B.' An electric current will then flow from the battery A to the wire of the cleetro-magnet B, because the other end of the wire of this electromagnet is always connected to the battery A through the wire A; \Vhen the electro-magnet B is thus energized, its armature B will be shifted over to the contact-piece b and an electric current will then pass from the battery D over the line-wires O G.

I will now describe the manner in which the swinging arm B is operated. B is a rod supported in the frame of the primary clock or regulator. Under it is arranged a rotary shaft, B, on which is afiixed a wheel,- B, having a cam-surface, I)", on one side. The lower end of the rod B is provided with an offset, b

that projects into the path of the cam surface If of the wheel B, and is adapted to extend under a projection, I), with which the swinging arm B is provided. The lower portion of the rod B is resilient. When the cam-surface I) of the wheel B comes opposite the rod B the latter will be sprung or moved aside. Its ofi'set b will then be moved from under the swinging arm B",aud the latter will descend so that its projection b will make contact with the offset b of the rod B. As soon as the cam-surface b 'has passed by the rod B, the latter will be ready to assume its original position and support the swinging arm B again. It cannot, however, assume its normal position until theswinging arm has been raised to its normal position. The swinging arm B will be raised to its normal position by a cam or eccentric, B on'the sweep secondshaft A. As the shaft A rotates rapidly, the swinging arm B will only be left in contact with the rod B momentarily. The shaft B is provided with a wheel, B, which has twenty-fourteeth. On the sweep second-shaft A a tubular minute-hand shaft, B, is arranged. This minute-hand shaft makes a rotation once every hour, and is provided with a wheel, B having asingle toot-h that engages once in each rotation with the wheel B and moves the latter a short distance. A spring-actuated tooth, B", which engages with the wheel B, insures the latter being moved a distanceequal to the distance between two adjacent teeth each time the wheel B engages with it. It also causes the movements of the wheel B to be made quickly each time it moves. The wheel B starts each movement of the wheel B, and the spring-actuated tooth B completes the movement quickly. This spring-actuated toothB also prevents the wheel B from movingimproperly. It will be understood from the de scription I have given that the wheel B, the

ISO

energized and will vibrate the lever 0".

shaft 13, andthe cam wheel B, rotate once each twenty-four hours, or,in other words, once a day. The circuit is therefore closed to the electro-magnet D but 011cc a day.

E designates the electric clocks or secondary clocks of the time-telegraph. They are arranged in multiple-arc circuit. Each has a shaft, 0, which is provided with a wheel, 0, having sixty teeth. bined with it a pawl-lever, e, which has affixcd to it an armature, c, for an electro magnet, c. The shaft 6 is a minute-shaft. In oth er words, it makes a complete rotation once every hour. The minute-hand of the clock is affixed to this shaft. Gearing is combined with this shaft to transmit motion to thehoun hand shaft. The hour-hand shaft I have not shown, as it has nothing to do with my invention. Every time an electric circuit is completed through the clectromagnet A, the latter will shift its armature A and cause an electric current to flow from the battery D to the electro-magnet c. The latter will thus be The pawls of the lever e will then move the wheel 6 and shaft 0 the distance of one tooth on said wheel. This will occur once every minute. The minute-hand will be moved in this way once every minute for the distance of a minute over the dial of the clock.

I will now describe the manner in which the electric current flows to each electro magnet (1*. One end of the wire of the electro-magnet e is connected with the line-wire (l and the other end of the wire of such clectro-magnets is connected to the line-wire G. Each time the sweep second-shaft A in its rotation permits the swinging arm A and the red A. to make contact, and the clectro-magnet A is, in consequence thereof, energized so as to shift its armature against the contact-piece a and an electric current flows from the battery D over the line-wires O G, the electromagnets c of the electric or secondary clocks will be energized. The pawl-levers will then be vibrated and will rotate the wheels 0 one tooth, causing the shafts c to carry the minute-hamls over the dials a distance sufficient to indicate one minute upon the dials. Each electric or secondary clock is provided with a tubular shaft, 0, fitting upon the shaft 6 and provided with a wheel, 0, having thirty one teeth. Combined with this wheel e is a pawl-lever, c. On the pawl-lever c the armature c of an electro-magnct,c,is mounted. One end of the wire of the electro-magnet 0" is connected to the line-wire 0-, and the other end thereof is connected to the line-wire 0. Each time the rotation of the shaft 13 of the primary clock or regulator effects a contactof the swing ing arm B with the rod B which will be once every day, the electro-magnct B will be energized so as to shift its armature B over against the contact-piece b, whereupon an electric current will be caused to pass from the battery D over the line-wires G t)". Then the electro magnets c of these electric or secondary This wheel 6 has com-- clocks will be energized, so as to attract their armatures e and vibrate the pawl-levers c. XVheels 6 will thus be moved one tooth. Calendar-hands on the shafts 6 will then be moved over the dial sufliciently far to point to the date of another day. Obviously the primary clock or regulator must be so organized that the swinging arm A cannot make contact with the rod A at the same time that the swinging arm B makes contact with the rod B Springs 0" retract the pawl-levers e" c of the electric or secondary clocks after they are severally retracted by the electro-magnets c 0". Steps 0, consisting, preferably, of ad just-able screws, are employed to limit the movements of the pawl levers.

I will now describe means whereby the electric or secondary clocks may be set from the oiiice where the primary clock is located. G designate keys consisting, severally, of a metal frame, 9, and a metal lever, g, journailed to the frame 9 and capable of being rocked up and down. The lever g is pro vided on its under side with a contact-piece. The frame gis provided beneath the lever with a contact-piece, gflwhich is insulated from the frame. A wire, G, extends from the rod B of the primary clock or regulator, and is connected to the levers g of the keys G G.

A wire, G, extends from the binding-post in which the wire B is secured to the contact piece 9* of the key G, and a wire, G, extends from the binding-post A, in which the wire A is sccurcd,to the contact-piece g of the key G. By depressing the lever g of the key G a communication with the battery A will be made from one pole along the wire A to the wire B", from the latter to the wire G, thence to the frame 9 of the key G, thence to the lever of the key, thence to the contact-piece of the key,and along the wire G to the wire of the electro-magnet I). As the other pole of the battery is always in communication with the wire of the electro-mngnet, the circuit is then complete. Each time the key G is thus operated the armature B will be shifted over to the contactpiece If, whereby an electric current from the battery D will energize the elcc-tromagnets c of the secondary. or electric clocks, so as to cause the latter to shift the pawl-levcrs e and through them the wheels 0' and calelnlar-hamls. in this way the calendar-hands of the electric orsecondary clocks may be set. By depressing the lever g of the key G a communication with the battery A will be made from one pole along the wire A to the wire B, thence to the wire G to the frame 9 of the key, thence to the lever g of the key, thence to the contact-piece of the key, from the latter along the wire G to one end of the wire of the electro-magnet A". The other end of the wire of the electromagnct- A being in communication with the battery A through the. wire A the circuit is complete. Whenever the key G" is thus operated, the electro magnet A will shift its armature A over against the eontaet'piece a and a current of electricity will pass from the battery D over the line-wires O C to the electro-magnet e of the electric or secondary clocks. Then the electro-magnets 6* will operate the pawl-levcrs c and cause the latter to shift the wheels 6 of the shafts e, carrying the minute-hands. Obviously galvanometers V may be combined with the line-wires O G (J in the otfice to indicate their electrical conditions.

I will now describe means whereby the elec tro-motive force will be sustained at points distant from the otfice where the battery D is located. I designates a supplemental battery connected at one pole by a wire, I, with the line-wire G and at the other pole by a wire, 1 and branch wires with the armatu res J 5 J of two elcctromagnets, J J The wire of the elect-ro magnet J is connected at one end with the line-wire O and at the other end with the line-wire O The armature J? is swung in one direction by the attractive force of the electro-magnet J and retracted by a spring, j. \Vhen attracted by the electromagnet, it is moved .over against a contact-piece, 2, which is electrically connected with the line-wire G Vhen retracted by the spring j, it is moved over against a contactpiece, t. The wire of the electro-magnet J is connected electrically at one end with the line-wire O and at the other end with the linewire \Vhen it attracts its armature J the latter is moved over against a contact-piece, i, which is electrically connected with. the line-wirc C. When retracted, it is moved over against a contact-piece, I. Then the electric current is caused to pass from the battery D over the line-wires O 0, the electromagnet J will be energized so as to attract its armature J, whereupon. a current of electricity will flow from the battery I over the line-wire I armature J, and contact-piece i to the linewire 0, and from the line-wire 0 back along the wire I to the battery I. Whenevcracurrent of electricity is caused to flow from the battery D over the line-wires O 0 the electromagnet J will be energized, so as to shift its armature J over against the contact-piece 1' whereupon the current of electricity will flow from the battery I over the wire I", armature J and contact-piece 6" to the line-wire C and back again from the line-wire O" to the battery. It will be seen that the battery I will always be automatically connected with the line-wires in such manner that its electric current will supplement the electric current traversing the line-wires from the main battery I). There may, of course, be any desirable number of supplemental batteries I combined with appurtenances such as I have described in con-- nation with other things, as hereinafter particularly specified.

I intend to .file applications for Letters Patent covering the novel features of my primary clockor regulator and the electric or secondary clocks.
